Log System Messages to the Router's Buffer or a Syslog Server
Capturing errors and events on a router and monitoring the console can be
critical to problem-solving. By default, the router doesn't send buffered
logging of its events to the router's memory. However, you can configure the
router to send buffered logging of its events to the memory.
Here's an example:
router(config)#logging buffered 16384
You could also send the router's events to a syslog server. Since it's
external to the router, there's an added benefit: It preserves events even
if the router loses power.
Note:
I have been told that 128000 is for core equip such as 6509, 12000, etc. for
small edge devices 1700 2600 3550 I have been told 4096 is what to set it at.
